1 Claim.

My invention relates to supports and more particularly to a type of support that may be employed for retainin charts or the like in a position for future reference.

The object of my invention is to provide a device that may be employed to retain charts such as are employed in recording instruments or the like, in a manner to aiiord visibility yet be securely held in place against a vertical board or wall.

Another object is to construct the device in a manner whereby the most recent chart is made visible and the others made accessible for reference.

The device is designed so that a plurality of units may be mounted adjacent one another to provide an orderly arrangement of records accessible to the user at all times.

Other and further objects of my invention will become more apparent as the description proceeds when taken in conjunction with the drawings, in which:

Figure 1 is a perspective view of the assembled device supporting a plurality of circular charts.

Figure 2 is a cross-sectional view of the device shown in Figure 1.

Figure 3 is a front view of the device mounted to a wall or board, and

Figure 4 is a cross-sectional view of the device, showing the pin mounted adjustable so that it may be placed into the center of the ring member.

Similar characters of reference indicate corresponding parts throughout the several views, and referring now to the same, the character i shows an annular ring hingedly supported at II in any convenient manner to a mounting arm l2, which in turn, is hingedly supported at I3 to a mounting b ock I4, which is attached to a board or wall l5. In Figures 1, 2 and 3, the board l5 has an outwardly extending pin I; attached thereto and this pin I6 is disposed centrally within the annular ring I0. The pin I6 is employed to su port the charts shown as H. These recording charts are provided with an aperture through their center and they are applied to the pin Is by extending the pin I6 through these apertures. The annular ring l0 may be made of any material but preferably of a transparent material, thereby allowing visibility and permitting the reading of the top chart while the device is in use.

Quite frequently, it is beneficial and sometimes necessary that charts from recording instruments be retained for future reference. The device as described affords a positive means of keeping the charts in proper order and permitting the latest chart to be visible for immediate observance. As the number of charts applied to the pin I6 in.

creases, the ring I 0 will be caused to extend outward from the board I5 and the radial movement of the mounting arm will cause the ring I0 to be raised. In Figure 4, I show the pin I6 mounted to a slidably supported member I8 arranged for vertical adjustment thereby making it possible to raise or lower the pin I6 for the charts I! in their relation to the ring I0. As shown, the board [5 is formed with a vertical slot I9 and overlying the slot a guide plate 20 is suitably secured, the latter being formed with a slot 2| in registry with the slot IS. The slidable member I8 is provided with a pair of studs 22 extended through the slot 20, the studs being headed, the inner head of the studs extending beyond the edges of the slot 2| so as to retain the member l8 upon the guide plate. It will be understood that the studs should have sufiicient frictional engagement with the guide plate 20 to maintain the member l8 in adjusted positions.

While I have shown a particular structure and specifically shown the arrangement of the component parts constituting the device, I am fully cognizant of the fact that many changes in the form and configuration of the various parts may be made without affecting the efficiency or performance of the device, and I reserve the right to make such changes as I may deem necessary and convenient Without departing from the spirit of my invention or the scope of the appended claim.

Having thus described my invention, what I claim and desire to secure by Letters Patent in the United States is:

A device of the character described, comprising an annular ring, a mounting arm, a vertical board, said mounting arm hingedly attached to said board at one end, aid ring hingedly attached to said mounting arm at the other end, a horizontal pin, said horizontal pin secured to a support, said support slideably mounted in said board, said pin extending outward from said support whereby said pin is vertically adjustable.

BEN WHITEHOUSE.
